The sacred texts mention that 'no one has unmixed happiness.' How does the story of Ratanji illustrate this teaching?

The story of Ratanji in Chapter 14 serves as a perfect illustration of the teaching that no one experiences 'unmixed happiness.' Ratanji was a man who seemingly had everything: vast wealth, property, and a reputation for being religious and charitable. To the outside world, he was 'swimming in an ocean of joy day and night.' Yet, the text reveals that 'the crocodile of a difficult inner worry always surrounded the merchant.' This worry was his lack of a son. This narrative demonstrates the 'divine plan' mentioned in the chapter, where even the most prosperous individuals have some nagging worry, preventing them from becoming arrogant and reminding them that material success does not equate to complete contentment.
